Numerical Studies of Weakly Stochastic Magnetic Reconnection
G. Kowal, A. Lazarian, E. T. Vishniac +1
We study the effects of turbulence on magnetic reconnection using three-dimensional numerical simulations. This is the first attempt to test a model of fast magnetic reconnection p…
Is J 133658.3-295105 a Radio Source at z >= 1.0 or at the Distance of M 83?
Horacio Dottori, Ruben J. Diaz, Damian Mast
We present Gemini optical imaging and spectroscopy of the radio source J 133658.3-295105. This source has been suggested to be the core of an FR II radio source with two detected l…
A Catalog of Extended Green Objects (EGOs) in the GLIMPSE Survey: A new sample of massive young stellar object outflow candidates
C. J. Cyganowski, B. A. Whitney, E. Holden +12
Using images from the Spitzer GLIMPSE Legacy survey, we have identified more than 300 extended 4.5 micron sources (abbreviated EGO, Extended Green Object, for the common coding of…
On the relationship between environment and galaxy properties in clusters of galaxies
Hector J. Martinez, Valeria Coenda, Hernan Muriel
We study the correlation between different properties of bright (L>L*) galaxies in clusters and the environment in the Sloan Digital Sky Survey (SDSS). Samples of clusters of galax…
Kinematics and physical properties of Southern interacting galaxies: the minor merger AM 2306-721
A. C. Krabbe, M. G. Pastoriza, Claudia Winge +2
We present an observational study about the effects of the interactions in the kinematics, stellar population and abundances of the components of the galaxy pair AM2306-721. Rotati…
Discovery of a [WO] central star in the planetary nebula Th 2-A
W. A. Weidmann, R. Gamen, R. J. Diaz +1
% context About 2500 planetary nebulae are known in our Galaxy but only 224 have central stars with reported spectral types in the Strasbourg-ESO Catalogue of Galactic Planetary Ne…
